Newborn animals gain immunity to diseases primarily by drinking which substance?

1. Milk

2. Water

3. Colostrum

4. Electrolytes

The correct answer is: Colostrum

Newborn animals gain immunity to diseases primarily by drinking colostrum. Colostrum is the first milk produced by mammals after giving birth and is particularly rich in antibodies, nutrients, and beneficial substances that are critical for a newborn's health. The high concentration of immunoglobulins, especially immunoglobulin G (IgG), in colostrum helps to protect the newborn from infections and diseases by providing passive immunity. This is crucial because newborns are born with immature immune systems and rely on the antibodies they receive from colostrum to help fend off pathogens in their environment during their early days of life. In contrast, regular milk, while it does contain some nutrients and antibodies, does not have the same high levels of these protective substances found in colostrum. Water is essential for hydration but does not contribute to immunity. Electrolytes, while important for maintaining fluid balance, also do not provide immune protection. Therefore, colostrum is the key substance that ensures a newborn animal receives the necessary immune support right after birth.
